This printer provides the RS-232/C and RS-422/A serial interfaces. The interface mode is
selected via menu.

Transmission Type

Data is sent and received in start/stop (asynchronous) transmission.

Character Format

Each character is transmitted in the following format:

1 START BIT + 8 DATA BITS + 1 PARITY BIT + 1 STOP BIT

The least significant bit of the data bits is sent first after the start bit. The number of data
bits is selected via menu. The parity bit, when present, follows the data bits. The start bit is
a logical "0" and the stop bit is a logical "1". The start and stop bits are used as character
framing bits.

Printer Connector

Male DB25 or equivalent connector.

Drive Capability

Max. 50 feet (15 m) for all supported data rates. The RS-422/A interface is effective up to
1200 m.
